Univision anchorman Jorge Ramos and five crew members were briefly detained on Monday at the presidential palace in Caracas, Venezuela.

The network tweeted on Monday evening that the team was at the Miraflores Palace "interviewing [Venezuelan President] Nicolás Maduro, but he didn't like the questions." They were "arbitrarily detained," and their "technical equipment was also confiscated." About 90 minutes later, Univision tweeted that the journalists had been released, and were back in their hotel.

Univision spokesman Jose Zamora told CNN Ramos was able to call the network and let them know what was happening, but "in the middle of the call, they took his phone away." The journalists were held for nearly three hours.

With his country descending into chaos due to hyperinflation and a lack of food and medicine, Maduro is facing calls to resign. The United States and dozens of other countries recognize opposition leader Juan Guaidó as interim president, and the U.S. announced new sanctions against Maduro and his allies on Monday.

On Wednesday afternoon, the Los Angeles Central mail facility was evacuated after an employee found a suspicious package addressed to Rep. Maxine Waters (D-Calif.), the Los Angeles Times reports.

The Los Angeles Police Department tweeted that it is working "closely with our federal law enforcement partners given the number of suspicious devices discovered across the nation."

Several packages with bombs inside addressed to high-profile Democrats, including former President Barack Obama and Hillary Clinton, as well as CNN, were uncovered on Wednesday. This was the second package addressed to Waters that was intercepted; the first was discovered in Maryland, headed for her office in Washington, D.C. The Times reports a robot is being used to examine the package found in Los Angeles. Catherine Garcia

On Monday morning, 23 people were injured after a "lava bomb" hit their tour boat off the Big Island, Hawaiian fire officials said.

An explosion sent molten lava flying through the air, and it burned through the boat's roof and damaged its railing. The boat returned to Wailoa Harbor, with 13 people having to be hospitalized and the rest treated at the scene. One of the victims is a woman in her 20s, who is in serious condition with a fractured femur, fire officials said. Witnesses told CNN they saw passengers getting off the boat with burns and gashes on their legs.

The Kilauea Volcano has been erupting since early May, and has destroyed dozens of homes. The boat was operated by Lava Ocean Tours, Hawaii's Department of Land and Natural Resources said. Passengers pay $220 for tours that show off the lava as it flows into the ocean. Catherine Garcia

Police in England are investigating whether a man and woman found unconscious in Amesbury were exposed to the same nerve agent that poisoned a former Russian spy and his daughter just eight miles away earlier this year.

The pair, both in their 40s, were discovered inside their home on Saturday. Wiltshire Police said it was first believed that the couple "fell ill after using possibly heroin or crack cocaine from a contaminated batch of drugs. They are both currently receiving treatment for suspected exposure to an unknown substance at Salisbury District Hospital." Several establishments the couple visited in Amesbury and Salisbury have been blocked off from the public.

Counterterrorism officials are investigating the case. In March, former Russian spy Sergei Skripal and his daughter, Yulia, were poisoned by Novichok, nerve agents developed by the Soviet Union and Russia, and BBC News reports the same government chemical weapons lab that identified Novichok in that case is working on determining the unknown substance the Amesbury couple encountered. Authorities say they are treating the case "with the utmost seriousness." Catherine Garcia

Doctors say more and more people are reporting that after being bitten by a Lone Star tick, they became allergic to red meat.

Ten years ago, there were just a few dozen known cases of the allergy, but "the range of the tick is expanding," Dr. Scott Commins told NPR, and he's "confident" there are now more than 5,000 cases in the U.S. Humans make a natural immune response to the alpha-gal sugar that animals produce in their bodies, and doctors are not sure what the Lone Star bite does to causes an alpha-gal allergy. "Whatever the tick is doing, it seems that it's a very potent awakener for our immune system to produce antibodies," Commins said. "And in this case, it's antibodies to this very particular sugar in red meat."

Lone Star ticks have been found in the Southeast, as well as New York, Minnesota, and Maine, and doctors say people who spend a lot of time outdoors need to protect themselves from the ticks. Once a person is diagnosed with an alpha-gal allergy, they are told to stop eating beef, lamb, and pork, and many who develop the allergy say they also have new issues with dairy. Laura Stirling, 51, told NPR that after being bitten by a tick, she ate pork sausage, and about six hours later she was covered in hives, had a stomachache, and felt lightheaded. She now has to avoid all meat and dairy. Commins said it is possible for people to get over the allergy, but "we need people to avoid additional tick bites for the allergic response to wane."

Update May 30: Arkady Babchenko showed up to a press conference on Wednesday, where he confessed to faking his death in order to catch his would-be assassin. Our original article appears below.

Veteran Russian war correspondent Arkady Babchenko was shot three times in the back as he left his apartment in Kiev, dying while in an ambulance headed to the hospital.

Ukrainian officials say it appears the gunman was waiting for the 41-year-old journalist to head out. A former Russian soldier who served in Chechnya, Babchenko wrote the memoir One Soldier's War, then covered conflicts in Georgia and Ukraine. After criticizing Russian President Vladimir Putin's annexation of Crimea and his support for separatists in Ukraine, Babchenko said he "no longer felt safe" in Russia and left in February 2017, settling in Kiev.

Ukrainian lawmaker Anton Gerashchenko said on Facebook that investigators will be looking at "Russian spy agencies," The Guardian reports, but Russian lawmaker Yevgeny Revenko pointed the finger right back at Kiev, saying: "Ukraine is becoming the most dangerous country for reporters. The Ukrainian government can't guarantee basic freedoms." Over the past few years, several critics of the Kremlin have been murdered in Ukraine, including Russian lawmaker Denis Voronenkov, who was shot and killed in 2016 while walking into a Kiev hotel.

A 5-year-old Colorado girl is recovering after being attacked by a bear outside of her home near Grand Junction early Sunday morning.

The girl's father, Duane Cyr, told KJCT his daughter will be "fine." Colorado Parks and Wildlife said the girl's mother reported that her daughter heard noises in the yard and believed they were coming from the family dog. It was actually a black bear, and when the mother heard screaming coming from outside, she ran out and saw the bear was dragging the girl. The mother said she began to scream at the bear, and it finally dropped her daughter.

Doctors said the girl had to have more than six dozen stitches, and her recovery could take several weeks, but she's in good spirits, KJCT reports. Catherine Garcia

The FBI is investigating several suspicious packages that were delivered to military and intelligence locations in the Washington, D.C., area, U.S. officials told CNN on Monday.

One official said more than 10 devices, all crude and involving black powder, arrived in packages at Fort McNair, Fort Belvoir, and the CIA. Had any of the packages exploded, the official added, they would not have been able to cause any fatalities. At least one package was sent to the National Defense University at Fort McNair, CNN reports, arriving in the morning. The package went through a scanning machine, and as soon as it was discovered to contain explosive material, the building was evacuated. No one was injured.

All of the suspicious packages are now being examined at the FBI's lab in Quantico, Virginia. Catherine Garcia
